I think the best answer that will describe chemical change is the first option. During a chemical change, b<span>oth the identity and the properties of a substance change because new substances are being formed by a chemical reaction. An example is rusting of steel</span>
Answer:
It depends upon the mass of the particles also. Assuming equal mass, then the slower moving particle gains some energy, and the faster-moving particle loses energy. However, if the slower moving particle had greater mass, it could transfer energy to the faster-moving particle.

Hope I could help! :)
Answer:
As the difference in electronegativity between two atoms decreases, the tendency for the formation of covalent bonds "increases"
Explanation:
Electronegativity being a chemical property which tells us about the tendency about the atom in order to fascinate the shared pair of the electron towards itself. It is being pretentious by atomic number and the distance as well, by the help of which the valence electrons resides from the charged nucleus. In the scale Pauling scale is used. Being the most electronegative element fluorine is counted. The more the electronegativity, the more electrons will fascinate towards itself.
Answer:
1
Explanation:
Consider the following reaction:
Phosphorus burn in the presence of air and produced diphosphorus pentoxide.
Chemical equation:
P₄ + O₂ → P₂O₅
Balanced chemical equation:
P₄ + 5O₂ → 2P₂O₅
Equation is balanced because there are four phosphorus atoms ans ten oxygen atoms in both side of equation.
Coefficient with reactant and product:
P₄ 1
O₂ 5
P₂O₅ 2
There is no coefficient written before P₄ it means only one P₄ is present.
